Gutshot,
A few years ago i came upon something similar while spotting. On the roadside we found a young buck that had just been hit by a car. He was still alive and struggling to get off the road and his one antler was just dangling by a flap of skin. A DCNR ranger came out and dispatched the poor little guy and discovered his skull had been baciscally cracked like a walnut shell. It was pretty gross but a real testament to just how tough a whitetail is.
